My recent blood results were TSH 4.29 & FT4 16.1 I am taking 50mcg levothyroxine and have been for 2 years. Following some research I believe I'm a case for T4 + T3 but my GP never agrees to refer me to the Endo who is the only person who can prescribe T3 as my GP surgery doesn't. So...back in March I did a 6 week test period taking 50mcg T3 (which I bought online) plus my usual 50mcg T4 and compared blood results...the test period results were TSH 0.44 & T4 12.7 & generally I did believe that I felt better. Following the latest blood results (the first ones I mentioned) my TSH levels are 0.09 over the guideline of 4.2 so my GP wasn't going to make any change to my medicine. I rang the GP & explained about the test period I ran myself & also some significant lifestyle changes I have made in the past 12 months & she agreed to refer me to the Endo. The Endo has written back to my GP to say there is no need to refer simply put my T4 meds up to 75mcg. I should add that my main symptoms are exhaustion, weight gain, loss of hair, loss of eyebrow hair & my toenails crumble away. Does anyone have any advice? Should I push to see the Endo or should I do another test period on T3 (buying it)?
